University of Birmingham scientists have analysed dust samples and found levels of organic contaminants higher than the median values found in US and western European homes.

The team said the findings could help guide the design and construction of future spacecraft.

Contaminants found in the ‘space dust’ included those used in many countries to meet fire safety regulations in consumer and commercial applications such as electrical and electronic equipment, building insulation, furniture fabrics and foams.

They also found contaminants typically emitted from the combustion of hydrocarbon fuels, the likes of which are used in space travel.

Forever chemicals, or PFAS, were discovered in the dust that are typically used in applications like stain-proofing agents for fabrics and clothing. However, their potential human health effects have led to some of them being banned or limited in use.

Professor Stuart Harrad, co-author of the study, said: “Our findings...
